gives a sense of a slight stutter in the motion,
indicating that 50 fps is not enough on this and other sequences with similar motion.

Objective Evaluation
Table 2 gives objective results for four of the test sequences evaluated subjectively in
the previous section. For the real sequences
Building
and
Control Panel
we
have created ground truth sequences by taking out every other frame of the inputs
and used these shortened sequences as frame doubling inputs, and for the artificial
ones we have simply created the ground truth frames. On the real sequences this
